Severe refractory Clostridium difficile infection with good response to fecal microbiota transplantation: a case report.

A 49-year-old woman diagnosed with pseudomembranous enterocolitis was transferred to our hospital for medical treatment. She responded poorly to treatment with vancomycin hydrochloride and metronidazole, so she underwent fecal microbiota transplantation. Treatment effects were observed the next day, and the diarrhea disappeared within 3 days. Colonoscopy 4 days later revealed the resolution of pseudomembranes, and no recurrences were reported within the first year after discharge.

Factors that affect the development of acute hemorrhagic rectal ulcer syndrome and rebleeding.

Objectives: Acute hemorrhagic rectal ulcer syndrome (AHRUS) causes massive bleeding and often recurrent rebleeding from rectal ulcers that form immediately above the dentate line. This study aimed to determine the clinical background and risk factors contributing to rebleeding in patients with AHRUS and the most appropriate method of hemostasis treatment. Methods: This retrospective study included 93 patients diagnosed with AHRUS at Showa University Fujigaoka Hospital, Japan, between April 2009 and November 2018. Information on clinical background factors, endoscopic findings, and hemostasis was obtained from medical records. The relationship with episodes of rebleeding was analyzed by multivariate logistic regression analysis. Results: The median age was 79 years, and 84 patients (90%) had a performance status of grade 2 or higher. The patients had multiple background factors, with a median number of 5 per patient. The background factors could be classified into two major factors: those related to arteriosclerosis and those related to delayed wound healing.In the multivariate analysis, significantly more rebleeding occurred in patients with active bleeding during the initial endoscopy (odds ratio 4.88, 95% confidence interval 1.80-14.46, p = 0.003); significantly less rebleeding occurred in patients for whom hemostasis was first performed by clipping (odds ratio 0.30, 95% confidence interval 0.09-0.88, p = 0.035). Conclusions: In bedridden older individuals with poor general health, multiple combinations of arteriosclerosis-related factors and protracted wound healing factors can induce AHRUS. We strongly recommend performing hemostasis via the clipping method on suspected bleeding points, including active bleeding sites, in AHRUS.

Carcinomatous cirrhosis as radiographically occult liver metastases of breast cancer: A systematic literature review.

In the present study, we aimed to clarify features of carcinomatous cirrhosis from breast cancer presenting as refractory transudate ascites and acute liver failure. In our systematic literature review, we identified 26 studies and 31 cases including our case of this rare condition. Our patient was a 49-year-old woman with a history of ascites and liver failure for the past 4 years and currently being treated for invasive ductal breast cancer. On radiography, she had occult liver metastases that were confirmed using laparoscopic liver biopsy. In the 31 cases, data on the reported year, age, type of primary breast cancer, time from breast cancer diagnosis, presence of ascites and/or varices, liver biopsy, diagnostic modalities, outcomes, and survival were documented and analyzed. All cases were reported during 1984-2020, with a mean patient age of 52.9 years. Eighteen patients (58.1%) were diagnosed with ductal breast cancer. Twenty-two patients (70.9%) had ascites. All patients had gradual progression to liver dysfunction. The following tests were performed: computed tomography (77.4%); ultrasound (58.0%); liver biopsy (100%); postmortem biopsy (35.5%), transjugular liver biopsy (32.3%), and laparoscopic liver biopsy (3.2%). Outcomes were reported for 29 patients, of whom 24 (82.3%) died after 1 day to 16 months. Invasive ductal carcinoma was the most common histological type; however, invasive lobular carcinoma was more frequent (32.3%) than its reported incidence in the breast. Carcinomatous cirrhosis has poor prognosis at relatively rash and is difficult to diagnose with usual modalities. It may be associated with E-cadherin loss or CD44 pronouncement.

Life-threatening emphysematous liver abscess associated with poorly controlled diabetes mellitus: a case report.

BACKGROUND: Emphysematous liver abscesses are defined as liver abscesses accompanied by gas formation. The fatality rate is extremely high at 27%, necessitating prompt intensive care. CASE PRESENTATION: The patient was a 69-year-old Japanese man with type 2 diabetes. He visited the emergency outpatient department for fever and general malaise that had been ongoing for 2 weeks. Abdominal computed tomography revealed an abscess 5 cm in diameter accompanied by gas formation in the right hepatic lobe. Markedly impaired glucose tolerance was observed with a blood sugar level of 571 mg/dL and a glycated hemoglobin level of 14.6%. The patient underwent emergency percutaneous abscess drainage, and intensive care was subsequently initiated. Klebsiella pneumoniae was detected in both the abscess cavity and blood cultures. The drain was removed 3 weeks later, and the patient was discharged. CONCLUSION: Emphysematous liver abscesses are often observed in patients with poorly controlled diabetes, and the fatality rate is extremely high. Fever and malaise occasionally mask life-threatening infections in diabetic patients, necessitating careful examination.

Successful conservative treatment of emphysematous gastritis.

Emphysematous gastritis is an extremely rare disease with an unfavorable prognosis. To date, very few studies have been conducted regarding the intragastric recovery process based on endoscopic findings. We herein report a case of emphysematous gastritis that improved with long-term (five months) conservative treatment in which we were able to observe the intragastric recovery process endoscopically. In cases in which emphysematous gastritis is suspected, it is important to provide prompt diagnostic imaging (including CT) and early appropriate treatment in order to improve the prognosis.
